First of all, it would require that you're using version 1.2.x of the RRDtool library. I guess it's safe to upgrade now, but back when I was putting the zoom stuff together, rrdtool 1.2 wasn't quite stable.
rrdtool 1.0 simply doesn't provide the information about the value range on the y-axis that is needed to implement the zoom. Tobi Oetiker who maintains the rrdtool library added this in 1.2 at my suggestion :-)
I'll look at reviving some old code I had to implement this. It requires some changes to both the hobbitgraph CGI and the zoom.js javascript code.

Sweet, I'm already using 1.2 so that'd be awesome if you could.

It looks like this may be in the latest snapshot. I grabbed it and put the hobbitgraph.cgi and zoom.js and put them in place. I tried it and it mostly works. The one thing I've noticed is it doesn't work as expected with multivalue graphs such as disks and memory. When you select and area, it still tries to show all the values regardless of whether the area selected contains the line.
